front mounted cooler - oil lines, what material? Options

[Bob Wolcott]

I have the shroud finished and I now need to route the oil lines back to the engine compartment. What material are the hard lines made of? Here are a few pictures of the lines in question.

Where can these lines be found, or do they have to be fabricated? Is there an easier way like running braided line instead of hard lines?

Thanks,
Bob

I would be able to machine brass ends to use with copper tubing, but what would be the best way to fasten them? Would plumbing solder be strong enough at oil temperatures or would they need to be hard (silver) soldered?
